Selecting a Caching Strategy
Apply the appropriate caching mechanism based on the data lifecycle and size requirements.
- If storing small, non-critical UI states or preferences: Use
shared_preferences. - If storing large, structured datasets: Use on-device databases (SQLite via
sqflite, Drift, Hive CE, or Isar). - If storing binary data or large media: Use file system caching via
path_provider. - If retaining user session state (navigation, scroll positions): Implement Flutter's built-in state restoration to sync the Element tree with the engine.
- If optimizing Android initialization: Pre-warm and cache the
FlutterEngine.

Implements animated effects, transitions, and motion in a Flutter app. Use when adding visual feedback, shared element transitions, or physics-based animations.
20flutter-building-layouts
Builds Flutter layouts using the constraint system and layout widgets. Use when creating or refining the UI structure of a Flutter application.
20flutter-managing-state
Manages application and ephemeral state in a Flutter app. Use when sharing data between widgets or handling complex UI state transitions.
20elixir-architect
Use when designing or architecting Elixir/Phoenix applications, creating comprehensive project documentation, planning OTP supervision trees, defining domain models with Ash Framework, structuring multi-app projects with path-based dependencies, or preparing handoff documentation for Director/Implementor AI collaboration
19flutter-working-with-databases
Manages local data persistence using SQLite or other database solutions. Use when a Flutter app needs to store, query, or synchronize large amounts of structured data on the device.
19flutter-architecting-apps
Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.
